I wrote a week ago that I had been advised that my knee pain from lifting was age related and that I should stop dead lifts and squats. The group suggested check with another PT. Some of yo might be interested in how this story ended...

I since found another PT who diagnosed Iliotibial Band Syndrome (IBT), He gave me a series of exercises, mostly focusing on stretching, and said cut back on the weight until the pain goes away and I spend some time stretching. Then increase weight s-l-o-w-l-y. It is early to say it is working, but I am improving.
